Microsoft 推出的桌面版应用程序,侧重于页面布局和图形设计。
Dear Shawn Xyu,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
As per your description, you want to know if Publisher supports inserting math formulas.
If the understanding above is right, as per the search and test on our side, we're afraid to tell that there's no out of box way supported for Math Formulas in Publisher currently. Given this, we'd recommend you use Word/PowerPoint as a workaround. Sorry for the inconvenience caused.
Personally, I completely agree with you, this is indeed a good addition to the current experience in Publisher. We’d suggest you go to Help > Feedback to send request for the feature within Publisher. Feedback submit by this way directly goes to the related team, this is the best way to let Publisher developers know your requirements and comments, help improve the product and make it better for you and others.
Sorry for the inconvenience again. Your patience and understanding are highly appreciated. Hope you stay safe and healthy.
Sincerely,
Rhoda | Microsoft Community Moderator
